Phoenix's new single Entertainment – the first to be taken from their forthcoming album, Bankrupt! – gallops out of the traps via a ludicrous synth riff that's part 80s children's TV theme and part David Bowie's China Girl after too many coffees. It's the sort of song that sounds so chipper on first listen that it must be masking a deep sadness, and that seems to be the case as singer Thomas Mars concludes the chorus with a surly sigh of "Oh, I'd rather be alone". Even the children's choir that arrives around the three-minute mark is just there to facilitate the gloom. For his remix – premiered here and available as a free download from the player above – producer Dev Hynes, AKA Blood Orange, slows the tempo, adds a meandering funk bassline and some echoey, downbeat drum claps and lets the inherent sadness slowly bubble to the surface. While the original careens around chasing that synth riff, Hynes's version shuffles the chorus to the beginning and replaces Mars's soft voice with the incredible harmonies of a certain Mutya Keisha Siobhan, who have recently been working with Hynes on their anticipated sort-of debut album (they're the original Sugababes, obviously). "I wanted to showcase how melodically brilliant the song was," Dev told the Guardian. "I was in the studio with MKS while I was working on the remix and their vocals along with Thomas's is like a dream to me." There's an amazing moment around the 90-second mark when the music drops out to leave a ticking beat underpinning the chorus as it glides in for the second time, and as MKS croon "I'd rather be alone", Hynes unleashes a completely OTT guitar solo that pierces the thick smoke like a laser. • Bankrupt! is due on 22 April via Loyaute/Glassnote/Atlantic Records.
